Remove all the atomic code besides MSVC and std::atomic

[ChangeLog][Important Behavior Changes] Starting with Qt 5.7, Qt
requires a C++11 compiler with support for C++11 atomics. This affects
user code too: Qt headers no longer compile with a C++98 compiler. The
minimum compiler versions for this release are:
 * Clang 3.4 (found in XCode 5.1)
 * GCC 4.7
 * Microsoft Visual Studio 2012
